Know thyself; this is the great object.
Authority founded on injustice is never of long duration.
Man is a reasoning Animal.
Where silence is not allowed, what then is permissible?
He is not guilty who is not guilty of his own free will.
Shall I tell you what the real evil is? To cringe to the things that are called evils, to surrender to them our freedom, in defiance of which we ought to face any suffering.
